“…The bands 623, 667 and 910 cm −1 are related to hydride bending. Finally, the bands in 2090 and 2110 cm −1 also related to the vibration of hydrides (Si-Hx) [25,24]. The red spectrum was obtained after immersion for 1 hour in 2% of 3-APTMS solution.…”

The content of biogenic amines has been studied due to the toxicity of these compounds in humans when are consumed exogenously, and is used as an indicator of quality in the food industry. The manly method for its determination is high performance liquid chromatography. However, it requires a long time for analysis. An alternative method is the use of biosensors, porous silicon with gold nanoparticles were obtained by electrochemical attack assisted with metal salt. These substrates were used for the construction of a biosensor capable of detecting BA using diamine oxidase enzyme as an element of biological recognition and is binding using the self-assembled monolayers method. The correlation between scanning electron microscopy, X-ray dispersive energy spectroscopy, and Fourier Transform infrared spectroscopy analysis, demonstrated the correct construction of the biosensor and the detection of biogenic amines by interaction with the enzyme. Finally, with the built biosensor it was possible to detect three important biogenic amines found in food.

“…Although oligomeric cyclic polythioethers possess excellent chelating ability, their preparation usually suffers from relatively low yield. [21][22][23] Thus, polythioethers of novel structures should be developed to enhance the yield.…”

“…The choice of these macrocyclic ligands is based on the inherent selectivity of thioether groups to soft and softmild transition metals, such as Ag + , Cd 2+ , Pb 2+ , Cu 2+ , and Zn 2+ [4]. Several studies aiming to develop applications for thiacrown ligands have been reported, including Hg 2+ chemosensor in water [5], competitive liquid-liquid solvent metal chelation [4], stabilizing unstable oxidation states such as Pd 3+ , Au 2+ and Ag 2+ [6,7], antitumor compounds [8][9][10][11][12] and protein kinase inhibitors [13]. Since the hazardous effects of free metal ions in the human body are numerous [14] (e.g., amyotrophic lateral sclerosis, kidney malfunction, cancer, Alzheimer's and Parkinson's diseases), a natural application of thiacrown ligands is in this area.…”

Structural and electronic properties of [C12H24S6X], [C13H26S6OX], and [C14H28S6OX] (X: Ag(+), Cd(2+)) crown thioether complexes were investigated within the framework of the density functional theory (DFT) using the projector augmented wave (PAW) method. The theoretical results were compared with time-differential perturbed γ-γ angular correlations (TDPAC) experiments reported in the literature using the (111)Ag→(111)Cd probe. In the case of X=Ag(+), a refinement of the structure was performed and the predicted equilibrium structures compared with available X-ray diffraction experimental data. Structural distortions induced by replacing Ag(+) with Cd(2+) were investigated as well as the electric-field gradient (EFG) tensor at the Cd(2+) sites. Our results suggest that the EFG at Cd(2+) sites corresponds to the Ag(+) coordination sphere structure, i.e., before the structural relaxations of the molecule with X=Cd(2+) are completed. The results are discussed in terms of the characteristics of the TDPAC (111)Ag→(111)Cd probe and the time window of the measurement, and provide an interesting tool with which to probe molecular relaxations.
